MACHINE FOR BORING TENONS.

SPECIFICATION forming part of Letters Patent No. 293,880, dated February19, 1884}.

Application tiled December 527, 1883. (No model.) I

T to whom it may concern: 7

Be it known that I, WILLIAM W. HosLER, a citizen of the United States ofAmerica, residing at Petoskey, in the county of Emmet and State ofMichigan, have invented certain new and' useful Improvements in Machinesfor Forming Tenons on Spokes and Boring and Drilling, of which thefollowing is a specification, reference being had therein to theaccompanying drawings.

This invention has relation to improvements in machines for formingtenons and drilling and boring purposes, and is available foroutwheel-spokes.

ting tenons on the ends of wheel-spokes when in their hub, orapplication to a work-benchwhen the object to be operated on is heldthereon; and it consists of the combination and arrangement of parts,substantially as hereinafter fully set forth and claimed.

In the accompanying drawings, Figure 1 is a side view of my improvedtenoning and boring and drilling machine as applied to one of itsusesth,e forming tenons on the ends of Fig. 2 is an enlarged detailview, partly in section; and Figs. 3 and 4 are also views in detailthereof.

In the organization of my invention I employ a stock or brace, A, thegreater length or portion of which is straight, while at one end it iscurveddownwardly and provided thereat with a cylinder or box, a, withinwhich is contained a sleeve, 0. The latter is confined in the box orcylinder, as against endwise movement, by an inwardly-projecting annularflange, 1), formed at the outer end of said cylinder, and by anapertured plate, 12, arranged at the opposite end of said cylinder orbox and bolted at'its upper end to the stock A.

B is the tool or chuck holder spindle, pass ing through the sleeve a andthrough the end plate, b, and the outer end of the box or cylinder a,the outer end of said spindle having a handle or crank, B, for turningthe same, while its opposite end has a chuck or tool holder, 0, appliedthereto,'said holder being sleeved and connected to the spindle by a setor holding screw, 0, extending through its sleeve and bearing againstthe spindle. The outer flared end is also provided witha set or holdingscrew, 0 to secure the tool or chuck designed to be held therein, toeffect the forming of a tenon,- or for drilling or boring purposes, asmay be demanded. In order to support theextreme inner end of the stockA, it

is provided thereat with a rest which consists of a straight uprightbar, 0, provided with a foot, 0. Said bar 0 is passed through a verticalslot, d, in the stock A, and is designed to be held therein by a set orholding screw, (1, said foot 0 thereof resting upon a spoke, as

seen in Fig. l, to support or retain properly in position that end ofthe stock.

D is a lever pivoted to, and also serving as q a support for, the stockA, its lower end resting on the floor, and being connected, near itsupper end, to the stock A, preferably by a staple or bail, e, and apivotal bolt or pin, 6, said staple or bail embracing the stock andfastened to the lever, while the pivotal pin or ing suitably connectedto the lever, the rest 0 is placed upon the spoke, and the lever D isdisposed in an upright position contiguously to the spoke, and moved soas to bring the tool or-chuck into contact with the spoke, and thereheld. By now turning the handle B of the spindle B, it is evident thatthe tool will be rotated and be caused to form a tenon on the spoke. Asthe operation of cutting the spoke continues, the tool or chuck is fedto its work by moviug, in the direction of cutting, the lever D, whichoperation is continued until the formation of the tenon is completed. Itis obvious that this machine can be adapted as well for drilling orboring purposes. I

\ Having thus fully described my invention, what I claim, and desire tosecure by Letters Patent, is

1. In a machine forforining tenons on spokes, the combination ofthestock A, having one end curved downwardly, to which is secured cylstockA, and strap E for securing the parts to the wheel-hub, substantially asshown and described.

3. A tenon-boring machine consisting of a stock or brace, a ehucleholdercomprising a spindle operated by a crank and secured to the stock byplate 1), bar 0, having foot 0, lever D, and strap E, substantially asshoivn, and for the purpose described.

In testimony whereof I affix my signature in presence of two witnesses.

\VILLIAM \V. HOSLER.
